Triex Minerals Corporation: Athabasca Basin Winter Drill Programs Complete

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 22, 2009) - Triex Minerals Corporation (TSX VENTURE:TXM) (the "Company") is pleased to announce that it has recently completed the winter drill program on the Pasfield Lake property in the eastern Athabasca Basin, Saskatchewan.

Property details, including ownership, location maps and results from previous programs, are available on the Company's website at www.triexminerals.com.

Two vertical holes were completed on the property, for a total of 2,116 metres. Both holes targeted the trace of the regional Cable Bay shear zone east of the lake, and east of the basement uplift block discovered under the central part of the lake during 2007 drill programs. Drill targets were the integration of surface geochemical anomalies with geophysical features, including basement conductors, gravity lows and changes in near-surface resistivity. Hole PF09-007 intersected the unconformity at 906 m, the "regional" depth of basement based on historic drill holes northwest of the property.

This drilling confirms the presence of a major regional shear zone east of the lake, and of hydrothermal fluids and extensive alteration along the structure. This drilling also confirms the complexity of the graben structures between the shear zone and the margin of the eight kilometre across basement uplift block under the lake itself. Further drilling is required to adequately test for uranium along the margins of the uplift block, and in the prospective but complex graben areas, especially where shallow basement is indicated by AMT geophysical surveys.

In Drill Hole PF09-007, iron staining and spotted hematite alteration was throughout Athabasca Group sandstone (see photo on the Company's website). Strong radioactivity (5 times background, and up to 600 cps) was measured over an extensive width (40 metres) immediately above the unconformity. More than 20 metres of pervasive chlorite alteration in fault breccia was intersected in the basement below the unconformity. In Drill Hole PF09-008, quartz and siderite veins, veinlets and veinlet breccias were throughout Athabasca group sandstone cover.

The significance of these results will be evaluated once geochemical data are in hand for uranium, and the key pathfinder elements for unconformity-type uranium deposits. Geochemical samples of core will be processed at the Saskatchewan Research Council Geoanalytical Laboratories in Saskatoon. A partial digestion preparation and fluorimetric XRF analysis will be used, with a check by total digestion preparation and ICP analytical finish. Drill holes were radiometrically probed using a down-hole Mount Sopris 2PGA-1000 poly-gamma probe.

The Pasfield Lake property remains a large and compelling exploration target, encompassing a major basement uplift feature located on a major regional shear zone, with strong surface geochemical anomalies and strongly altered and radioactive rocks discovered in drill core on both sides of the lake, that is, on both the eastern and western "arms" of the Cable Bay Shear zone. More drilling is required to follow-up results to date and adequately test the strike length of the key structural targets on the property.
